str = strings returns a string scalar with no characters, "".

str = strings (n) returns an N×N string array whose every element has no characters.

str = strings (sz1, …, szN) returns a string array of size sz1-by-…-by-szN, and str = strings (sz) takes the same sizes as the row vector sz.

A size may be numeric or logical, and must be a real, finite integer. A negative size counts as zero, as does an empty size argument, and an empty size vector gives a 0×0 array.

The elements are strings with no characters, not missing strings, so ismissing is false and strlength is zero for every one of them. string (cell (sz)) gives missing strings instead.
